Sweet looking welds; TIG?

 

[lehr]

Yes tig but not as sweet as your avatar !

 

[RonRock]

[GillandCo]

I would love to show you a fully OEM numbers matching car, but.. I took it apart 20 plus years ago and have been dragging it around for what seems like forever. Time or money never have both. Some day....

Maybe you should just travel from town to town welding brewstands and keggles for us. You could probably drink yourself to heaven and back with free homebrew if you took it up.

Those welds are awesome. I just bought a Northern Tool Flux Core welder and so far my welds look like little balls holding metal together. Soldering I can do, welding, not so much.

...yet.

Sounds like a good plan and a new tv show "Man vs Fabrication"

Timm turn the heat up if your making balls see if that helps.

Thanks Pat

Great looking welds, what gauge are those tank walls?

I'd say about 16ga.

What's the tape on the fittings for, not the teflon, are you back purging? Also is the brass to absorb heat and to help distortion? That's what I do, I don't back purge as I don't have a splitter for my regulator.

I wish I were a buddy of yours.

The duct tape is for back gassing the teflon is to test for leaks with water.
I'm going to get some caps for those fittings so I dont have to put tape on the ends because it melts.

Your are my buddy you just live a long ways away !

Can you get me a pic of your back purge(back gas) setup? When I did some pipe welding a long time ago, I back purged, but forget how the argon came off of the bottle. Wondering what I have to buy to have back purging capabilities.
Thanks,
Morgan

Morgan I have two tanks one has just a flow meter for back purging. I run that hose through one of the fittings and I use tin foil behind the fittings taped around the edges to seal it off.

what size tungsten do you use?

Good question I think a 1/16 some where around there.

[Dog House Brew]

I figured as much. My smallest is 1/8" and it's a bit much for keg/coupling welding. Works, but too much heat required.

 

[macdadmorgan]

I use 3/32 and it works the best, I have a hard time using 1/8" for anything less the 1/4" thick stock.

Your are my buddy you just live a long ways away !

I'm closer Pat......=o&o>......

What does the inside weld look like?, is it ground and polished smooth.

No you dont have to do that if you back gas.

Dude with your skills you don't need any help from me !

I dont think I have ever welded anything that thick with my tig but aluminum.
I do think you could weld a keg with 1/8th inch once you got your amps right.

So the inside does not get back welded and ground like this then http://picasaweb.google.com/kevin.ladue/KegglesForClubMembers#5194106467776001890.
